Description

[0002] Steel pipes are tubular steel materials widely used in industries such as construction, machinery, petroleum, and chemical engineering. They can be classified in various ways according to production processes, materials, shapes, etc., and are mainly divided into two categories: seamless steel pipes and welded steel pipes. A device for measuring the length of steel pipe couplings is a device used to accurately measure the length of steel pipe couplings.

The measurement system obtains the length of the steel pipe coupling by calculating the round-trip time of the light beam.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0032] Refer to Figure 1 - Figure 2, an embodiment provided by the utility model: a steel pipe coupling length measuring device, which includes a workbench 1. A support column 2 is fixedly connected to the lower surface of the workbench 1, and the support column 2 is used to support the entire device. A fixed rod 3 is fixedly connected inside the workbench 1. A sliding block 4 is slidably connected to the side wall of the fixed rod 3, and the sliding block 4 is used to drive the fixing plate 5 to move. A fixing plate 5 is fixedly connected to the upper surface of the sliding block 4. An installation block one 6 is fixedly connected to the upper surface of the fixing plate 5, and the installation block one 6 is used to install the clamping plate 7. A clamping plate 7 is fixedly connected to the side wall of the installation block one 6, and the clamping plate 7 is used to clamp and fix the coupling. A fixed block one 8 is fixedly connected inside the workbench 1. A rotating disk 9 is rotatably connected to the side wall of the fixed block one 8. A rotating rod 10 is rotatably connected to the side wall of the rotating disk 9, and the other end of the rotating rod 10 is rotatably connected to the upper surface of the fixing plate 5. A hydraulic rod 11 is fixedly connected inside the workbench 1, and the hydraulic rod 11 is used to pull the fixing plate 5 to slide. The output end of the hydraulic rod 11 is fixedly connected to a connecting block 12, and the side wall of the connecting block 12 is fixedly connected to the lower surface of one side fixing plate 5. A laser distance measuring sensor 15 is fixedly connected to the side wall of one side clamping plate 7, and a distance measuring plate 25 is fixedly connected to the side wall of the other side clamping plate 7. The length measurement of the coupling is realized by the cooperation of the laser distance measuring sensor 15 and the distance measuring plate 25;

[0033] During the process of measuring the length of the coupling, first, the coupling needs to be placed on the fixed block two 14 of the device. Subsequently, the operator needs to start the hydraulic rod 11. Through the contraction action of the hydraulic rod 11, the connecting block 12 is driven to move accordingly. The movement of the connecting block 12 will further pull the sliding block 4, causing it to slide along the guide rail. The sliding of the sliding block 4 will cause the fixing plate 5 on one side to move accordingly, thereby driving the clamping plate 7 to make a corresponding displacement. The movement of the clamping plate 7 will cause the rotating rod 10 to rotate, and the rotation of the rotating rod 10 will drive the rotating disk 9 to rotate. As the rotating disk 9 rotates, the rotating rod 10 on the other side will also rotate accordingly, thereby driving the fixing plate 5 on the other side to slide, and finally causing the clamping plate 7 on the other side to also move. Through this series of actions, the coupling is successfully clamped and fixed on the device. Next, in order to measure the length of the coupling, the operator needs to turn on the laser distance measuring sensor 15. The laser distance measuring sensor 15 is an existing device and will not be elaborated here. The laser beam emitted by the laser distance measuring sensor 15 will irradiate on the distance measuring plate 25. The distance measuring plate 25 is an existing device and will not be elaborated here. The distance measuring plate 25 is provided with specific marks or scales. After the laser beam irradiates on the distance measuring plate 25, the distance measuring plate 25 will calculate the distance between the clamping plates 7 according to the reflected laser signal. By accurately measuring the distance between the clamping plates 7, the actual length of the coupling can be finally obtained. This measurement process is not only fast but also accurate, greatly improving the work efficiency and ensuring the reliability of the measurement results.

[0034] Refer to Figure 3 - Figure 4, on one side of the clamping plate 7, a third fixing block 16 is fixedly connected to the side wall. A protective sleeve 17 is arranged on the side wall of the clamping plate 7. The protective sleeve 17 is used to protect the laser distance sensor 15. The side wall of the third fixing block 16 is slidably connected inside the protective sleeve 17. An auxiliary component for placing the coupling is arranged on the upper surface of the workbench 1. The auxiliary component includes a first fixing sleeve 13. The lower surface of the first fixing sleeve 13 is fixedly connected to the upper surface of the workbench 1. A second fixing block 14 is fixedly connected to the upper surface of the first fixing sleeve 13. A clamping groove 24 is formed inside the protective sleeve 17. The side wall of the third fixing block 16 is slidably connected inside the clamping groove 24. A second fixing sleeve 18 is fixedly connected to the upper surface of the protective sleeve 17. A sliding rod 19 is slidably connected inside the second fixing sleeve 18. One end of the sliding rod 19 is fixedly connected to a connecting plate 20. The other end of the sliding rod 19 is fixedly connected to a second mounting block 22. A spring 21 is sleeved on the side wall of the sliding rod 19. The spring 21 is used to drive the sliding of the sliding rod 19. One end of the spring 21 is fixedly connected inside the second fixing sleeve 18. The other end of the spring 21 is fixedly connected to the side wall of the second mounting block 22. A clamping block 23 is fixedly connected to the lower surface of the second mounting block 22. The clamping block 23 is used to clamp the third fixing block 16. The side wall of the clamping block 23 is slidably connected inside the third fixing block 16.

[0035] When the laser distance sensor 15 is not needed to be used, first, slide the third fixing block 16 into the inside of the clamping groove 24. When the third fixing block 16 slides into the inside of the clamping groove 24, a certain pressure will be exerted on the clamping block 23. This pressure will cause the sliding rod 19 to slide along a specific direction. The sliding of the sliding rod 19 is driven by the contraction of the spring 21. The spring 21 plays a very crucial role in this process and can contract under the action of the third fixing block 16, thereby providing power for the sliding rod 19. When the sliding rod 19 slides to the groove position of the third fixing block 16, the spring 21 will lose the extrusion effect on the sliding rod 19. However, it is at this moment that the elastic force of the spring 21 will suddenly be released, pushing the sliding rod 19 to continue sliding. This sudden pushing force will cause the clamping block 23 to be clamped into the groove of the third fixing block 16. In this way, the clamping block 23 is firmly locked in the groove, thus realizing the fixation of the protective sleeve 17. In this way, it can be ensured that the laser distance sensor 15 is fully protected when not in use, avoiding damage caused by external factors, thereby prolonging its service life and ensuring the accuracy of measurement.

[0036] Working principle: When using this device to measure the length of the coupling, first place the coupling on the second fixed block 14. Then, by starting the hydraulic rod 11 to make it contract, the connecting block 12 is driven to move, thereby pulling the sliding block 4 to slide, causing the fixed plate 5 on one side to drive the clamping plate 7 to move, making the rotating rod 10 rotate, driving the rotating disc 9 to rotate, and making the rotating rod 10 on the other side drive the fixed plate 5 to slide, so that the clamping plate 7 on the other side moves, and then the coupling is clamped and fixed. Then, by turning on the laser distance sensor 15, it irradiates on the distance measuring plate 25 to measure the distance between the clamping plates 7, thereby measuring the length of the coupling. When the laser distance sensor 15 is not needed, by sliding the third fixed block 16 into the inside of the card slot 24, it squeezes the card block 23, making the sliding rod 19 slide and the spring 21 contract. When sliding to the groove of the third fixed block 16, the spring 21 loses the extrusion and thus pushes the sliding rod 19 to slide, and the card block 23 is inserted into the groove, thereby fixing the protective sleeve 17 to achieve the effect of protecting the laser distance sensor 15.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
